Serial No. 128,534.

This' invention relates to rear end doors for Y house cars and among the objects of the invention may be mentioned the provision of a structure so designed as to closely t its openings and effectively close the end of the car during the severe usage to which it is put and means for easily and effectively securing the door in closed position.

The invention comprises the novel structure and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

Figure 8 is a view similar to Figure 7 illustrating a modification of such structure.

Figure 9 is an enlarged fragmentary sectional view illustrating a lower portion of the car and door and showing the manner in which the locking rod may be secured.

In referring to the drawings which illustrate one embodiment of this invention, there is shown in Figure 1 the rear end of 'a car which is closed by a pair of doors 1 and 2 involving this invention. In the presentA instance, these doors are shown as consistingof spaced walls 3 and 4 with suitable channel bars 5 therebetween against which the walls are united or secured. :Each door is secured to a lateral margin of the door opening by a plurality of hinges pwhich may be of the gusset plate type.

The upper and lower margin of each door comprises a Z bar 7 (Figure 2) the respective flanges of which are secured tothe opposed walls of the doors.l A wooden bar 8 lor the like is secured in the exterior angle of each Z bar 7. The lower bar 8 is bevelled at its lower surface as indicated at 9 to Awedgingly lfit within the door Opening which is provided with a suitable sill member 10 having an upwardly sloping flange 11 within the door opening which cooperates with the bevelled or sloping surface 9 on the bar 8. A Z bar 12 which is secured to the upper margin of the door opening affords a seat for theupper wooden bar 8 which fits in the lower angle thereof. as shown in Figure 2.

The `inner walls 3 of the doors which are preferably'made of metal are bent outwardly. at their outer lateral margins as indicated `at 13 in Figure 5, and they are secured to the outer wall 4. The portion 13 slopes outwardand cooperates with an inwardly sloping ange 14 of a channel member 15 at the lateral margin of the door opening:v It should be noted that the lateral margin 16 ofeach door extends beyond the offset portion 13 and normally abuts the channel member 15 whereby the weather is effectively excluded.

The inner wall 3.of the door is provided with an outwardly offset terminal 17 (Figure 4) at its inner margin .which is secured to the louter wall 4. A vertical plate 18 is secured tothe inner margin of the door 2. This plateV hasy an inwardly slopingl portion V19 which" terminates in a form of trough 20.

The inner wall of the doorl 1 is also provided with an, outwardly offset terminall7 which is secured to the outer wall 4. A plate 21 is secured Ito the inner margin of the door 1 and is provided with a rearwardly sloping flange 22 having a bent terminal 23 which fits in the trough of the plate 18 whereby a weather tight joint is provided.

A vertical locking rod 24 1s pivoted upon the door 1 and swings as indicated in dotted lines in Figure 1 for engagement with keepers 25 and 26 which are respectively secured 100 to the bottom and top portions of the car. The rod 24 consists of a flatplate 27 upon which a ribbed plate 28 is secured. The rib which is indicated by the reference 28.n tapers `from a medial point toward the ends so-that the ends are sub-stantially fiat for ready insertion under the keepers 25 and. 26, as indicated by the shaded portion in- Figure 4.

` The manner of pivoting the rod- 24 to the doorl is best illustrated in Figure 4. In referring to said figure it will be noted that a.

through the door 1 to which it is bolted. Obviously the bearing 32 will 'frictionally engagev the rod 24 and may rotate or swing therewith, since it is rotatably mounted in said bearing socket.

In Figure 7 there is shown the keeper 26 having an underhanging flange or lip 26a for engaging the projecting rib 24b of a metal member 24a Instead of the interengaging parts.24b and 26a 25a under which lever 1s connected as shown in Figure 7, the locking rod 24 and keeper 26 may be providedwith interengaging beads 45 and 46 as shown in Figure 8. The bead 45 may be formed of rivet heads or the like, whilethe bead 46 may be formed by inwardly crimping the lower end of the 'keeper 26. In Figure 9 is shown the manner of securing the lower end of the locking rod 24. It will be noted that the keeper 25 is provided with an inwardly overhanging liangeA or lip a foot 47 on ythe lower end of the rod engages. i understood any similar interengaging parts may be used. Due to the iupper interlocking parts 24'b and 26` and the lower interlocking parts 25n and 47, the locking rod 24valso ties b the upper and lower parts. of the car to-4 gether and serves as a tension member' when the upper and lower parts of the car tend to spread apart, and as a compression member when such parts tend to come together or contract. v

Mechanism has been provided for swinging the rod 24 to bring its ends under the keepers 25 and 26 or remove the same" therefrom. This mechanism consists of a bell crank lever 34 (Figure l) pivotedrat its heel to the'door 1, referably adjacent the lower portion thereof.) One arm of this bell crank by means of a link 35 with the. rod 24. The other arm of this bell crank lever is in the. form of an operating handle 36 having a slot for receiving a hasp 37 where- 24 which eX- tends under the overhanging bearing 32 and secured to the top of the rod 24.

It should however, be

by the lever may,be sealed or locked in closed posltion against operation. When the locking means are removed and the handle 36 is freed from the has itmay be swung as shown inl vdotted line position to swing the rod 24 for unlocking the doors. To limit the swinging movements of the rod 24, proper stop clips 38 may be placed upon the doors as shown in Figure 1, to prevent the swinging movement of the rod beyond such stops.

The door 2 is 39 slidably maintained in a suitable bearing 40. This bolt is adapted for engaging a keeper 41 on the bottom of the car whereby the door may be latched after it has been closed and before the door 1 has been closed and the rod 24 operated. This latter bolt will also secure the lower portion of the door in -proper position against the car.

In order to tie the side plates of the car to the end plate above the aforedescribed doors, a pair of angle clips42-are secured to each side. plate adjacent the ends thereof. lAn angular gusset plate 43 has a horizontal ange 43a riveted to the outstandin flanges of the angle clips and a depending ange 43h which is riveted to theend plate 44 and to the Z bar 12, and terminates at the end of the endplate 44.

It will be appreciated that/the particular construction heretofore described possessesl excellent weathering features due 'to the bevels on the doors and the coaction of the front plates 19 and 2l, and due to the spaced walls of the doors, withstand the strain but nevertheless light to avoid excessive weight. At the same time, a novel operating mechanism for the locking rod has been provided and means whereby the mechanism can be locked against unauthorized use.

I am aware that many changes may be made, and numerous details of construction varied through a wide range without departing from the principles of this invention, and` I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated y the prior art.
